Here is a small HowTo, helping you to put the dictionary as a separate icon in the section area

Open the file /config/application.config and add this line just before the </applications> <add alias="dictionary" name="Dictionary" icon="dict.png" sortOrder="7" />

Open the file /config/trees.config and add the following line at the end, just before </trees> <add application="dictionary" alias="dictionaryApp" title="Dictionary" type="umbraco.loadDictionary, umbraco" iconClosed=".sprTreeFolder" iconOpen=".sprTreeFolder_o" action="openDictionary()" sortOrder="0" />

Last, add a new icon in the following directory /umbraco/images/tray. I’ve added a very simple, which you can download and save at the appropriate location. Save this file as “dict.png”.

Enable the section for user who needs this separate dictionary sectionTo do so, find the user in the users section. Then mark the checkbox for this dictionary and save.
